LITERATURE REVIEW LIMBACHIYA AND LEELAWAT found that recycled concrete aggregate had 7 to lower relative density and 2 times higher water absorption than natural aggregate. according to their test results, it shown that there was no effect with the replacement of coarse recycled concrete aggregate used on the ceiling strength

Oct 28, In this paper, a comprehensive literature review was conducted on the utilization of recycled concrete aggregate (RCA), which is the dominant construction and demolition waste material, in base and subbase layers and its comparison with natural aggregate

According to a few research findings, using Recycled Aggregate Concrete reduces building costs. It is recognized as a building material. When recycled aggregate is employed, the amount of virgin aggregates produced is reduced, resulting in less usage of natural resources. Recycled aggregate concrete can be used in a variety of

Abstract. The present state of knowledge on the use of recycled concrete as an aggregate in new concrete is reviewed and suggestions made as to what further work is necessary before a proper assessment of the material can be made. Where crushed uncontaminated concrete is used the properties of the material as an aggregate and the basic
